[PATCH v2] mtd: rawnand: meson: replace integer consts with proper defines

[Arseniy Krasnov]

Add defines for column address. It makes driver more readable, because
bitwise OR with 0 looks useless.

Suggested-by: Liang Yang <liang.yang@xxxxxxxxxxx>

 Changelog:
  v1 -> v2:
   * Use defines with zero values instead of dropping both operations in
     v1.
